The electrostatic series helps predict what property of materials in relation to electricity?

• A. Their color change in an electric field
• B. Their tendency to produce magnetic fields
• C. Their attraction or repulsion to electrons (electron affinity)
• D. Their melting point

Answer: (C)

The key idea is how easily a material tends to gain or lose electrons when it touches another material. The electrostatic series orders materials by this tendency, so you can predict which one will pull in electrons (becoming negatively charged) and which will give up electrons (becoming positively charged) after contact or rubbing. In other words, it tells you about electron affinity in the context of charging by contact. It doesn’t describe color changes, magnetic effects, or melting points, which are governed by other properties.
